Abstract

This paper presents a tuned mass damper (TMD) utilizing a parametric design technique to reduce the dynamic responses to seismic loads of retractable large spatial structures. An artificial intelligence algorithm was developed to automatically search for the installation position of the damping device. This enables confirming the dynamic response of the structure in real time while finding the optimum position for the damping device. Further, the optimum mass of the damping device is determined from among several alternatives, and a design that can be effectively applied to both open and closed conditions of the roof is obtained.

본 논문는 개폐식 대공간 구조물의 지진하중에 대한 동적응답을 줄이기 위한 목적으로 파라메트릭 설계 기법을 적용한 TMD에 관한 연구이다. 인공지능 알고리즘을 이용하여 감쇠장치의 설치 위치를 자동 탐색하는 컴포넌트를 개발하였다. 이는 구조물의 동적응답을 실시간으로 확인하고, 구조물의 감쇠장치 최적의 위치를 찾을 수 있을 있다. 또한, 여러 대안에 대한 감쇠장치 질량의 최적 값을 찾아주며, 지붕의 열린 상태와 닫힌 상태에 모두 효과적으로 적용될 수 있는 설계안을 찾을 수 있다.
